Quote: "The rotation operation does not have an inverse. Since some amount of distortion is unavoidable when rotating an image by an amount that is not a multiple of 90 degrees, rotating an image clockwise, then counterclockwise by the same amount does not completely restore the original image. To rotate an image in a reversible way, set its angle property instead of using the rotate command. Unlike the rotate command, the angle property affects only the screen display of the image, not the actual picture data in it." Unquote. ;-) -- Jeanne A. E.
